Hmm...
Good points:
*Superb artwork
*Great voices (what's up with all these pelicans? lol)
*Lots of original concepts (avoiding the pelicans, dropping different presents for girls and boys, naughty houses etc.)
*Good music
Bad points:
*You lose too many points for missing a chimney/earn too few points for hitting one
*What's up with the exploding houses?
*You should be able to drop the presents on any part of the house and not just the chimneys (or at least make the damn things bigger)
*More obstacles (power lines, tower blocks, different types of birds...maybe houses with two or more children?)
*Every second you spent on this game is a second you could have spent working on Killing Spree VII.
Summary: Not a waste of time, far from it, but the gameplay mechanics need some refinement. 3/5 6/10 and looking forward to Killing Spree VII.
